Why is this the answer?

The answer is fate because this is a wonderful puzzle about something very big that we all have, but we cannot see or touch it. Fate is another word for your future, or what is going to happen to you. It is the special, secret plan of your life that you start to discover every single day as you grow older. Let us look closely at the first clue: "It's in your hand though you can not feel it." This part of the riddle is playing a fun trick with words. When the riddle says "in your hand," it does not mean something you can physically hold like a toy or a pencil. Instead, it means that your future, or your fate, is something you have control over right now because of the good choices you make. Think of the saying, "The ball is in your court," which means you get to choose what happens next. In the same way, the power to shape your life is metaphorically "in your hand." You cannot feel your fate with your fingers, but every choice you make today, like being kind to a friend or working hard on your schoolwork, is helping to build your tomorrow. You own your fate from the moment you are born. The second part of the riddle gives us a big hint: "Only you and time can reveal it." This means you cannot just look up your future in a book or on a screen. You cannot look into a magic crystal ball to see exactly what your fate will be right now. The only way to find out the amazing story of your life is to live it, one exciting day after another. The passing of time is what slowly "reveals" your fate, step by step. It is like reading a chapter of a book at a time. As you grow up and time passes, all your dreams, your hard work, and the kind things you do will become the special story of your life. That wonderful story is your fate, and only by spending time being you will you ever know what happens next.
